Calm have built the technology to detect when you're experiencing stress through analysing heart rate, perspiration, blood pressure and movement.

If we recognise that you're reaching a stress level, we send an alert and ask you to engage in a breathing exercise.

Calm uses a breathing exercise that is scientifically proven to reduce stress levels, and we keep breathing with you until you're heart rate returns to a safe and healthy state.

Initially designed to help you fall asleep in under one minute, the "4-7-8 Breathing Exercise“ is also effective in rapidly reducing your heart-rate.

The movement of the Calm Droplet is designed to focus your mind whilst you concentrate on your breathing. It also gives you live bio-feedback on your decreasing heart rate.
